Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed June 19, 1916. Serial No. 104,372.

To all whom it may concern:

Be it known that 1, JAMES MoGovERN, a citizen of the United States, residing at Taunton, county of Bristol, State of Massachusetts, have invented a certain new and useful Improvement in Combination Coal and Gas Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

Many people prefer to use coal as a fuel during a portion of the year, especially during the colder weather, and to use gas as the fuel during certain other seasons especially during the warm weather when they do not desire to have a continuous fire. This is particularly true in the use of kitchen ranges and in order to avoid both the eX- pense of having two ranges, one for coal and one for gas, and the necessity of having a storage place for the one not in use, it has come about that combination ranges are employed which can be used for either coal or gas.

this class. 7

Certain provisions have to be made for circulation and other purposes to adapt the range for gas which are not required when coal alone is used. In order to heatthe oven with the gas burner the best resultsare obtained by having the burner about on a level with or below the lower part of the oven and to provide a deflector whichshall deflect the heat from the burner intothe oven. Sometimes the burner has been located along side of one end of the oven extending from front torear thereof beneaththe firepot for the coal and a flue passage is provided for conducting the heat from the burner into the oven. A preferable arrangement, however, is to locate the burner entirely on the front side of the ovenin connection with the oven shelf and one object of my invention is to provide a burner disposed in this manner. It is also important, when so constructed and arranged, to provide a combination shield and defiectorwhich shall protect the cook from danger of coming in contact with the burner when she opens the oven door The present invention relates to stoves of.

When coal is to be used instead of gas, this shield and deflector is unnecessary and one object of the invention is to make the shield and deflector removable and to provide a removable cover plate which when the said deflector is removed may be inserted to cover up the gas burner and to close the flue from the burner to the interior of the oven. If, however, it is desired to use both coal and gas at the same time, as is sometimes the case, the deflector plate will be allowed to remain in position just the same as when used for gas alone and coal may also be used at the same time in the fire pot.

The invention will be fully understood when taken in connection with the accompanying drawings and the novel featuresthereof will be pointed out and clearly defined in the claims at the close of this'specification;

In the drawings, Figure 1 is a vertical section from front to rear of a range embodying the invention showing the interior of the oven and the parts adapted for use with gas. Fig. 2 is a section similar to Fig. 1 but showingthe parts adapted for use with coal as a fuel. ,Fig'. 3 is a front elevation partly in section showing the parts in the same position asin Fig. 1. Fig. 4 is a detail perspective view of the deflector plate. Fig. 5 is a detail perspective view of the oven shelf. Fig. 6 is a detail perspective view of the cover plate for the recess in the oven shelf.

Referringnow to the drawings, 1 represents the fire potfor coal, 2 the grate for the fire pot, 3 the ash pit and 4 the oven. The lower front part of the oven has a forwardly extending portion 5, and the oven door 6 has corresponding forwardly extending portion 26. The oven has the fixed bottom portion 7 which extends from the rear to the front of the body portion of the oven. The said forwardly extending portion 5 has at its bottom the slottedoven shelf 8 which is preferably bowed downwardly, making a trough shaped chamber or recess 9 below the level and in front of the said oven bottom 7 to receive the gas burner pipe 10 which extends through one end wall of the oven shelf into the said recess. The said burner pipe 10 has an extension portion 11 outside of the recess which connects with the gas supply pipe 21 and is provided with a cock 12 to control the admission and shutting off of the gas. The oven shelf has an open work bottom preferably something like a trough shaped grate, havlng open spaces 28 to admit air to aid combustion. One edge of the oven. shelf 8 rests upon the flange 22 and the shelf is attached to the flange 22 by bolts 23 which can easily be removed to permit the oven shelf to be detached if desired.

ing lips 24, 25. The upper surface of said 7 plate 13 is on a level with the upper face of the oven bottom 7. hen gas is to be used,

the said plate 13 which lies free on its seat will be removed and the combination shield and deflector plate 15 is inserted. This deflector plate rests on lugs 16 formed on the sides of the oven walls a short distance above the bottom in a; similar manner to the lugs usually'provided for supporting the oven racks and can be easily removed and reinserted, The said plate 15 reaches forward over the oven shelf '8 and recess 9 at some distance. above the oven shelf, and has a downwardlycurved forward portion17, its forward end extending down and resting upon the said even shelf 8 on. the forward side of the chamber 9 back of the lip 25 and where the forward edge of the plate 13 is supported when said plate 13 is employed. This defiector plate with its turned down forward portion thus entirely shields the burner at the front and performs the double purpose of protection against any one accidentally coming in contactwith the burner whenthe oven door is open and to deflect the current of hot air toward the rear part of the oven. Said deflector plate 15 as clearly shown in Fig. 1 does noteXten'd entirely to the rearof the oven, but leaves a passage 27 sothat the hot air which passes to the rear under the plate 15 rises behind it into the upper part of'the oven. Preferably also saild plate 15 is formed with a plurality of apertures 18 near the side edges to create circulation and permit some of the hot air to rise through the plate near the front and rear oven plates without passing by way of the pa ag 7- 19 representsan ordinary oven rack supported on lugs 20. At the upper part of the oven are the circulation openings 21 through the wall of the oven.

While I have described the slotted oven shelf aspreferably having the bottom bowed downwardly, I wish it to be understood that I do not intend to be limited to the bowed shape, the important feature being that it shall be slotted or formed with open work to admit air, and thatit shall hold the burner.

Vhat I claim is:

. 1. A combinedcoal and gas stove havin an oven shelf secured to the front part 0 the oven bottom and projecting outside of the body of the stove, said oven shelf being formed with a trough-shaped depression to receive a gas burner, said depressed portion having a plurality of slots in its bottom and having an end opening to receive a gas pipe, said shelf also having a flange portion which extends forwardly of said depressed portion.

2. A combined coal and gas stove having an oven shelf detachably secured to and suspended from the main front part of the stove and level with the oven bottom and projecting outside of the body of the stove, and formed with a trough-shaped pocket or depression to receive a gas burner, said pocket having an open top adapted to open into the oven and having in its wall vent openings and an opening to admit a gas burner pipe. a

3. An attachment for a coal burningrange whereby said range may be converted into a gas burning range, said attachment consist- 7 ing of an oven shelf formed with a pocket in its upper face, open at the top and having vent openings in its wall and an opening to admit a gas burner pipe and means for se curing said shelf to the front part of the oven bottom outside of the body of the stove.

1. A combined coal and gas stove having an oven shelf secured thereto which serves also as a gas burner holder, said oven shelf being formed with a trough-shaped depressed portion integral therewith formed with vent openings and with an opening in one end of said depressed portion to admit a gas burner pipe, said shelf also having a flange portion which extends outwardly and downwardly upper part of said depressed portion.

In testimony whereofI afliX my signature, in presence of a witness.
